Keywords

A keyword is a variable that you can use to specify a package version number.

You can use two different keywords to automatically increment the value of the package build numbers and set the package dependency to the latest version.

Use the NEXT keyword to increment the build number to the next available for the package.

1"versionNumber": "1.2.0.NEXT"

Use the LATEST keyword in the version number to assign the latest version of the package dependency when you create a package version.

1"dependencies": [ 
2   {
3      "package": "MyPackageName",
4      "versionNumber": "0.1.0.LATEST"
5   }
